CHECK-CONTROLLED insole-DELIVERY APPARATUS.

SPECIFICATION formingpart of Letters Patent No. 737,091, dated August 25, 1903.

Application filed October 24, 1901. Serial No. 79.827. (lTo model.)

To all whom it may concern:

Be it known that I, HARVEYFELDMEIER, a

citizen of the United States, and a. resident of Littlefalls,-in the county of Herkimer and State of New York, have invented new and useful Improvements in Check-Controlled Liquid-Delivery Apparatus, of which the following is a specification. f

This invention relates to thatclass of liquid delivery or dispensing apparatus which embody a pump the action of which is controlled by checks, tokens, or similar devices in such manner thatthe delivery of liquid begins only after the insertion of a check,

token, or other controlling device and is stopped automatically when the value of the check or other controlling device is exhausted and which respond to checks of different values, so that the apparatus will deliver a greater or less volume of liquid in accordance with the greater or less value of the check which is inserted. y

The object of this invention is to produce an .apparatus which is independent of the unit-delivery of "the pump, but depends for the control of the delivery upon the actual distance traveledby the pum p-piston,whether greater or less, and in which the ratio which the movement of the check bears to that of the piston can be readily changed, so that the value of the checks or, in other words, the volume of liquid'called for by the checks can be readily changed as circumstances may require.

In the accompanying drawings, consisting of three sheets, Figure 1 is a frontclevation of a check-pump provided with myimprovements, the door of the casing of the check mechanism being removed. Fig. 2 is an end elevation of the pump. Fig. 3 is a top plan view of the same. Fig. 4 is a rear elevation of the upper part of the check-pump on an enlarged scale. Fig. 5 is ahorizontal section in line '5 5, Fig; 4, on an enlarged scale through the rock-lever and connecting parts which connect the pump with the check-propelling mechanism. Fig. 6 is a sectional elevation of the chain mechanism connecting the rock-lever with the check-propelling mechanism. Fig. '7 is afront elevation similar to Fig. 1, but on an enlarged scale, of the check-propelling mechanism. Fig. 8 is a Fig. 13 is a verand the' check-guide in line 13 13, Fig. 8.

Fig. 14 is a perspective view of the locking and unlocking arms of the check mechanism. Fig. 15 is a perspective view ofa check with short propelling and delivery faces.

Like letters of reference refer to like parts in the several figures.

A represents the upright pump-frame; a, the vertical cylinder of a single-acting or lifting pump of any suitable construction secured to said frame in any suitable manner;

a,.the pump-piston a the piston-rod; 0. the

hand-lever by whichthe piston is actuated and which is pivoted to the top of the frame by a pivot a and a links which connect the short arm of the hand-lever with the upper end of the piston-rod. The upper part of the frame is formed by a housing A, in which the check propelling mechanism is supported.

This housing also forms the check-till'and is provided on its front side with a door A which is secured by a suitable look, so that access can be had only by authorized persons.

The check-propelling mechanism is actuated by a shaft B, which is rotated intermittently forwardly and backwardly in unison with and proportionate to the linear recipro cating movement of the piston. The actual intermittent linear movement of the piston is reproduced on this shaft as a corresponding intermittent rotary back-and-forthmovement andis transmitted from this shaft to the check propelling mechanism and by the latter to the check or other controlling device. This shaft is arranged horizontally in the housing A and is journaled in a bearing 1), formed on the rear wall Z) of the housingand projecting rearwardly and forwardly therefrom, as most clearly shown in Fig. 11.

The mechanism by which the shaft B of the check mechanism is actuated from the piston is constructed as follows:

C represents a rock-lever, which is fulcrumed on a pivot-bolt (Z on the rear side of the casing A and which has a long arm a connected with the piston-rod by any suitable means, so that the lever is oscillated by the reciprocating movement of the piston, and a short arm 0, by which the shaft B is actuated. As shown in the drawings, the long arm of the lever is provided with abifurcated end 0 which engages the bolts 0 by which the lower ends of the links a are connected with the head 0 of the piston-rod. The short arm 0 of the lever is provided with a bifurcated end 0 which engages a bolt eon a vertically-reciprocating sleeve or head E, which is connected by a chain or other flexible connection 6 with a drum e on the rear end of the shaft B, Figs. 4, 5, 6, 8, and 11. The sleeve or head E slides up and down on a rod e secured in lugs e on a frame a which is secured to the rear side of the casingA. The sleeve or head may, however, be guided in any other suitable manner.

The rocklever C is provided with any suitable means for changing the relative length of its two arms, so that the ratio of motion which is produced at the short arm of the lever and communicated from the latter to the check-propelling mechanism can be increased or reduced. Two different. means for changing the ratio of motion are shown in the drawings, Figs. 4 and 5, and both can be used conjointly in the same apparatus. One of these means consists of several pivot-holes cl, formed in the lever in such manner that either hole may be engaged with the pivot bolt (I. These holes are so located or spaced that theyproduce certain desired different ratios of movement. Another means for changing the ratio of movement consists of a horizontal slot f, formed in the bracket F, in which the pivot-bolt (Z of the rock-lever is adjnstably secured. By shifting the pi vot-bolt in this slot the leverage can be nicely adjusted. The several pivot-holes (1 provide an adjustment to certain predetermined positions of the lever and corresponding ratios of movement, and the slotf provides a fine adjustment intermediate of or irrespective of these fixed positions and ratios.

The chain 6 extends from the sleeve E upwardly and over the peripheral face of the drum 6 to which the end of the chain is secured, so that the downward movement of the short rear arm of the lever and of the head E unwinds the chain from the drum e and turns the latter and the shaft B in the direction of the arrow in Fig. 4:. During the upward movement of the rear arm of the lever the drum and shaft are turned in the opposite direction and the chain is wound upon the drum by any suitable return device-for instance, a spring g, Figs. 8 and 11'-Which is coiled around the shaft in the casing A and connected at one end with the shaft and at the other with the casing.

7t represents a pawl'arm which is secured to the shaft B near the front end thereof and which carries a pawl h. The latter engages with a ratchet-wheel H, which is mounted loosely on the shaft B in front of the pawlarm and which receives an intermittent rotary motion from the pawl 7t and is held against backward movement by a detentpawl 7L2.

t' represents actuating arms, cams, or projections formed on the ratchet-wheel for actuating a pawl I, by which the check K or other token or delivery-controlling device is propelled.

The checks used in this apparatus are strips or flat bars of metal having on one of the longitudinal edges a propelling-face 7r, provided with a series of ratchet-teeth with which the propelling-pawl I engages, Figs. 7, 10, and 15, and at the opposite edge a plain back which forms the delivery-face of the check.

716 76 represent beveled faces formed on the front end of the check, the beveled face k leading to the toothed propelling-face k and the beveled face k to the delivery back or face 7c.

L represents the check-guide, which has the form of a flat rectangular tube extending downwardly from the top plate of the casing A on the front side of the ratchet-wheel H, and on one side of the center thereof, Figs. 1, 7, 8,10, 11, and 13. This check-guide is preferably formed by a channeled barZ and a front plate Z, which latter covers the channel ofthe bar. The upper end of the check-guide is preferably covered as a finish by a faceplate Z which has a slot Z for the insertion of the check.

1, Figs. 7 and 12, is a rock-lever which is pivoted to the front plate of the check-guide at t" and which extends underneath the actuating-arm 2' and is depressed by the latter. The propelling-pawl I is pivoted to this rocklever and extends upwardly from the same and projects with its tooth or head into the check-guide through a notch m. The propelling-pawl is drawn toward the toothed propelling-face of the check by a spring i The rock-lever l. is pressed upwardly against the actuating-arm by a spring i, which is at? tached at its upper end to the check-guide.

M is a detentpawl which is pivoted to the check-guide above the notch m and which has its head or tooth arranged in this notch above the head of the propelling-pawl. This detent-pawl is pressed toward the check bya spring m.

The hand-lever by which the pump is actuated is locked against movement in the normal position of the parts by a locking-arm N, which is arranged in the housing A and ILO IIO

which projects with its head a through an opening at in the rear wall of the housing into engagement with a toothed segmentniformed on the locking-lever concentric with the pivot thereof, Figs. 7, 8, 9, 13, and 14. This locking-arm is secured to the upper end of a vertical rock-shat t 07. which is journaled in bearings 01/, formed on the inner side of the casing. N represents an unlocking-arm, which: is secured. to the same rock-shaft below the locking-arm and which is provided at its end;

with a pin M, which projects into a notch 0,

formed in thatedge of the check-guide, against which the delivery face of the check bears. The teeth on the segment n are arranged on the front side of the segment, which faces the rear wall of the housing A,.so that the head of the locking-arm N is concealed by the segmen t.. The locking-arm is held yieldingly in engagement with the segment and theunlocking-arm within the unlocking-notch in the path of the check by a suitable spring. As shown in the drawings, a spring 19 is secured for this purpose to the inner side of the casing, so as to bear against the front side of the locking-arm and hold the arm against the toothed segment and the unlocking-arm in the notch o of the check-guide, as shown in Figs. 8 and 9. In the normal position of the parts the pump-lever is locked against movement v path of the check,as represented in Figs. 9 and 10. The propelling-pawl I and the detent-pawl ton.

M stands with their heads in the notch m of the check-guide, as shown in Fig. 10. For operating the pump the check is inserted in the check-guide and pushed down in the same until theupper end of the check is flush withthe face-plate Z The checks are 'made of such length that when the check has been so inserted its beveled front face W has passed by the propelling-pawl I and has swung the samesidewise sufficiently to engage the pawl strokes orpartial strokes, as the operator may desire. The oscillating movement of the pump-lever causes an intermittent progressive rotation of the ratchet-wheel H, each movement of the ratchet-wheel being proportionate to the effective movement of the pis- The progressive intermittent movement of the ratchet-wheel produces'a corresponding progressive forward movementof *propellingpawl I, is caused to make two ef-.

pawl is. made for each revolution of the wheel, and when more than two arms are employed a correspondingly greater numberxof propelling strokes are made. The check is propelled in this manner'by a succession of downward movements through the checkguide until the propelling-pawl reaches the upperend oflthetoothedpropelling-face of the check, which end is preferably on a level with the upper end of the plain back or'de.

livery-face of the-check. When the propelling-pawl has made the downward stroke in engagement with the last tooth of the propelling-face of the check, the pin a, at the end of the unlocking-arm N, clears the upper end of the delivery-face and moves inwardly under pressure oft-he spring 19, thereby engaging the locking arm N withthe vlocking-segment,whereby the pumpis locked against further movement until another check is inserted. The spent check remains in the lower part of the check-guide with its propelling and delivery faces below the head of the propelling-pawl and the pin of the unlocking-arm and is pushed out of theguide by the insertion of thenext following check. The

propelling and delivery faces of the checks are a made of greater or less length,according to the desired value of the check. When these faces are shorter than the required length of the check, the latter is provided above these faces with an extension 70 Fig. 15, of proper length and so narrow that it does not come in contact with the pawls and unlocking-arm.

The rear portion of therock-lever. O and the chain mechanism connecting. the same with the oscillating or rock shaft B are pref erably covered by a casing Q, which is indi pelled proportionately to the distance trav-:

eled by the piston or other displacement mom ber of the pump,whether such piston or member travels the full distance of its movement or only a fraction thereof. The holder of the check is thereby enabled to procure the full. volume of liquid called for by the checkfwithe out reference to .the length of the pis tonstroke and can take long or shortstrokes in working the pump, as maybe most conven- The ratio which the movement of the check bears to that of the piston, and, consequently the delivery value of the check, can be readily changed. by simplyadjusting the.

, rock-lever C as described without interchanging any parts or introducing any new parts. By this means the delivery value of the check is changed without changing the stroke of the piston, thereby retaining the full delivery capacity of the pump at a full stroke under all the different values which maybe given to the check. In the apparatus illustrated and described herein the delivery is stopped by locking the pump against further movement. This means of stopping the delivery is very satisfactory; but other means may be resorted to, and I do not wish to limit myself to this particular means.

The check-propelling mechanism and the mechanism for transmitting the piston movement to the check-propelling mechanism herein described and shown are very satisfactory in their operation and are preferred; but these mechanisms may nevertheless be modified in various ways without departing from the essence of my invention.
